| Headline Details: NyxSat is a 3U CubeSat designed for educational purposes and amateur radio services. The project is a collaboration aimed at teaching Chilean engineers, technicians and students how to build, integrate, and operate a satellite, covering the entire mission life cycle. The satellite provides two main services to the amateur community: a standard UHF digital repeater with "store-and-forward" capability. It will store messages from radio amateurs and redistribute them within the periodic beacon (one message per beacon). In addition, it will carry an innovative LoRa Digipeater to allow the ham community to test long-range, low-power links via satellite. This protocol is relatively new in the amateur satellite service and will provide a modern platform for experimentation. At the same time the satellite will carry two scientific experimental payloads: an optical payload that will monitor light pollution over Chile, specifically near astronomical observatories, and a new deployable solar array and EPS, developed by the University, that will be validated in orbit. Being the main scope of the mission educational, all communications are non-encrypted and public, specifically UHF will be used for TM/TC including also the LoRa segment. In addition, S-Band will be used for images downlink. Following the heritage of TigriSat, STECCO, AstroBioCubeSat and our other satellites we will provide the amateur community with all the instructions and tools, also through a dedicated webpage, needed to decode the telemetry and images from the satellite: many radio amateur regularly publish Tigrisat telemetry on Twitter and on Sat-amateur websites (i.e. https://www.dk3wn.info/wp/satelliten/tigrisat/). Data will be available online for free consultation, and we will implement a QSL card system to acknowledge contributors and reports. The communication segment is overseen by a licensed radio amateur, in addition the School of Aerospace Engineering has its own HAM Callsign IU0SIA. Proposing UHF downlinks using 9k6 GMSK and also 250bps LoRa, plus, on S Band, 1 Mbps QPSK. Planning a 500 km SSO but no launch date or agency has yet been finalised.
